Abstract
This experiment was applied in Al-Hussainiya district in Karbala governorate. The experiment was for the pierod 6/1/2022- 11/4/2022. The aim of the study was the effect of adding zeolite with and without urea on the performance of Awassi lamps and investigates its effect on the rumen fluid. Sixteen sheep with 3-4 months of age with 18 kg weight have been used in the experiment. This number was divided into four treatments. The first treatment was fed the control treatment without any added, while the second treatment was fed with 3% zeolite, the third treatment was 3% zeolite, 1.5% urea, and the fourth treatment was 3% zeolite and 3% urea. The factorial experiment using the complete randomly design randomized design has been used to analysis the data. The results have been showed that no significant differences at the level of p<0.05) in the primary weight rates among the experimental groups. There are significant differences in the final weight, as the third and fourth treatments were significantly superior to the level of (p<0.05), which were (37.35, 37.90) kg, respectively, while the control treatment was (31.80) kg. As for the second treatment, it was not significantly superior (p<0.05) with the first treatment, but it was superior to the first, which reached (31.80) kg. Also, the third treatment was superior to all treatments in the daily and total weight gain. There were significant differences (P<0.05) in the total increase among the experimental treatments. The treatment added to its diets T3 (3% zeolite 5.1% urea) superior with other treatment, which reaching (20.10) kg, while the control was (13.45) kg. In addition, there were no significant differences (P<0.05) in the average of the concentrated feed for the different experimental treatments, but there were arithmetic differences, as the first, second, third and fourth treatments, which reached (87.53, 86.59, 69.33, 77.08) kg, respectively. There are significant differences (P<0.05) between the different experimental treatments that were fed with wheat, where the animal was given 300 g/day. Also, no significant differences (P<0.05) found in the consumption of total feed provided to Awassi sheep. Finally, there were significant (P<0.05) differences in the efficiency of food conversion between the different treatments, where the first treatment superior the control at (P<0.05), which reaching (7.68) compared with the third treatment 5.37.
